Last week, at a private event held at the Hollywood Bowl, L-Acoustics announced the new L Series line array with its patented Progressive Ultra-Dense Line Source (PULS) technology. Having debuted at the BRIT Awards with pilot phase partner Britannia Row/Clair Global, on tour with Helene Fischer and pilot phase partner Solotech, and at Coachella with support from RAT Sound, L Series will continue its pilot phase validation before it becomes available in production this fall.

L-Acoustics introduced the modern line array concept in the 1990s and today it is the standard for live events around the world.

“L Series is a breakthrough concept in concert sound that is made possible through the culmination of 30 years of intensive R&D in software modeling, loudspeaker technology, and electronics,” says Germain Simon, director of product management, loudspeakers at L-Acoustics.

Josh Lloyd, Britannia Row head of engineering and special projects and BRIT Awards’ front of house engineer says “L Series was truly impressive in terms of its coverage consistency, it was nearly impossible to hear any transition between elements of the array,” adding that “the tonal consistency was incredible; every listener had the same audio experience. The cardioid behavior of the box meant that once moving out of the coverage zone, it was difficult to tell if the system was on!”

The operating efficiencies of L Series originate from its shape. With no inter-element angles, a pin-less auto-lock rigging system, and a single cable connector, the simple set-up environment reduces errors and leads to a three-fold decrease in loading time versus a similar K2 configuration.

L Series is just as impactful on the environment as it is on deployment and is also frugal in truck space and consequently in fuel consumption.

 “Our L2 system uses a fraction of the truck space as an equivalent K1/K2 system would have,” explains Holger Schader, senior consultant concert touring and special events at Solotech, who is touring with Fischer. “We used just one truck instead of two trucks for the audio on this tour. Load in is also easier and more fail safe because we only have four elements to connect instead of 16.”

L Series ships in Q4, 2023.
